iPod/iPhone/iPad/iPod Touch run-time with i10s/i10
With the iPod Nano 3G, the i10s/i10 is capable of running up to 12 hours streaming Bluetooth music. For iPod classic, iPod Touch, iPhone, iPad, the run-time is much longer due to the bigger batteries in these devices.
In below, iDevice = iPod/iPad/iPhone/iPod Touch.
The run-time depends on:
1) Whether you keep the iDevice LCD display on, and the brightness you set the display. For best run-time, turn down/off the LCD display. 2) The Audio volume you set on the iDevice, the higher the volume, the shorter the run time. 3) The distance between the i10s and the receiver, the further the distance the shorter the run time. 4) Any objects (or human body) in the path of the i10s and the receiver, if objects (or human body) between i10s and receiver, the shorter the run time. 5) How new the iDevice battery is. If the iDevice battery is new, the run time will be longer. If the iDevice battery is old, the run time will be shorter. 6) How the iDevice battery was initially and subsequently charged/discharged. Please refer to iDevice user guide for the best practice in charging, discharging an iDevice battery. For most batteries, there is also a burn-in period for the battery before you get the best battery performance. 7) The particular iDevice model and/or generation, as different models/generations of iDevice have different capacity batteries.
